The easy rule is to clean showerheads whenever you can see mineral buildup or a slimy film. That buildup can make it easier for germs to grow inside the fixture.
The CDC says you may need to remove the showerhead and hose and soak them in white vinegar or a similar solution to loosen buildup. The EPA also recommends checking the manufacturer’s instructions and cleaning more often if you see scale.
If the showerhead has a lot of buildup, let it soak, scrub away loosened deposits, rinse it well, and reinstall it. Regular cleaning matters more than a fancy cleaner.
If someone in the home is at higher risk from waterborne germs, be extra careful about maintenance and follow official guidance closely.
The short version: clean on sight, soak when needed, and do not ignore scale.
A reliable showerhead cleaner is a small investment that makes this easier: showerhead cleaner.
